Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523910, here are decompositions:

29 + 31523881 = 31523910
59 + 31523851 = 31523910
71 + 31523839 = 31523910
107 + 31523803 = 31523910
109 + 31523801 = 31523910
149 + 31523761 = 31523910
157 + 31523753 = 31523910
241 + 31523669 = 31523910

Showing the first eight; more decompositions exist.
